An electronic hooter is an electrical signaling device designed to produce a loud and clear audible sound to alert personnel about specific conditions, such as faults, emergencies, or operational changes in industrial, commercial, or residential setups. Unlike mechanical hooters or bells, electronic hooters use electronic circuitry to generate sound, allowing for more consistent tone, volume, and duration. They can operate on AC or DC power supplies, with various voltage ratings depending on the application. -Technical Specs : 1. Input Voltage : 12Vdc, 24Vdc and from 100 Vac/vdc to 260Vac/Vdc 2.
